The problem to be solved by the present invention is to provide a power supply system and a moving object capable of reducing switching loss and steady-state loss compared with the prior art. In order to solve the problem, this power supply system (1) is provided with: a variable-voltage power supply (7) that outputs power of a variable voltage (E1) from secondary-side input/output terminal pairs (72p, 72n); and a first power line (21) and a second power line (22) that connect the secondary-side input/output terminal pair (72p, 72n) and a load (4). The power supply system is characterized by comprising: a first switching unit 31 provided on a first power line 21; a third power line 23 connecting both ends of the first switching unit 31; and a bypass line (25) connecting the secondary side input/output terminal pairs (72p, 72n); wherein a first DC power source (38) for outputting DC power is provided on the third power line (23), and a bypass diode (33a) for allowing the output current of the first DC power source (38) and blocking the reverse current thereof is provided on the bypass line (25).
本发明要解决的问题是,提供一种与以往相比可以降低开关损耗及稳态损耗的电源系统及移动体。为了解决上述问题,本发明的电源系统1,包括:可变电压电源7,从二次侧输入/输出端子对72p,72n输出可变电压E1的电力;及,第一电力线21及第二电力线22,连接二次侧输入/输出端子对72p,72n与负载4;所述电源系统的特征在于,包括:第一开关单元31,设置在第一电力线21上;第三电力线23,连接第一开关单元31的两端;及,旁通线25,连接二次侧输入/输出端子对72p,72n;其中,在第三电力线23上设置输出直流电力的第一直流电源38,在旁通线25上设置容许第一直流电源38的输出电流且阻断其逆向的电流的旁通二极管33a。
